I don't ever see it recommended on here. My license is coming to an end for Norton on my xp computer and don't know whether there is something better. It seems to stop a lot of stuff, I see warnings like "deep throat trojan" etc has been stopped...sounds good. Do all firewalls block this type of stuff? I'm currently testing OP pro on an old win 98 computer, but am finding it a bit confusing. Why does it say open ports, I'd rather it said stealthed. Also sometimes it says "one or more components of this application have changed" and gives me options and I'm afraid I don't really understand the details. Think I'm going to have to find something else.
